Carbon steel seamless elbow procurement and cleaning issues

We should think twice about buying things, especially for the quality to pass, the quality is good, in addition, to understand the price, there is the production process, and there is for some time after the use of cleaning is in place, these are the need to consider

Look at the following places when buying elbows

Next Xiaobian I bring you some suggestions to help you buy excellent carbon steel seamless elbow products, first of all, to determine the purchase of carbon steel seamless elbow technical parameters, that is, the caliber of the elbow, and its elbow specifications, pressure level may be wall thickness, pressure level, and wall thickness can be calculated

Then is the material of the elbow, followed by the anti-corrosion problem, the elbow does not need to be painted or sprayed.

Some bad pipe fitting manufacturers use unreliable materials, usually determining the specification is the amount of nickel, you can use the potion to distinguish, but obviously, this is also a disadvantage, because the small furnace material containing nickel is only 7 more and is unlikely to distinguish, but the price gap of raw materials is relatively large, it is one of the false.In particular, 321 high nickel and 316 high nickel false is very serious. Therefore, when buying an elbow, we must pay attention to the material problem of the elbow. To ensure the quality of the elbow, I suggest finding a reliable and safe manufacturer.

If customers need to do anti-corrosion treatment, we must do, many manufacturers on the market are not doing solid solution treatment and high penetration non-destructive testing

In this, there are also many spraying instead of rolling sand. After eliminating these processes, the manufacturer will greatly control the cost, reduce the quality of the elbow, and the price will be lower than that of the same industry, thus enhancing the probability of order.

Many bad carbon steel seamless elbow manufacturers fake in endless, the above is a small series of me to introduce you when buying elbow must pay attention to the problem, I hope to help you buy real material carbon steel seamless elbow products

How should carbon steel seamless elbow be cleaned

Carbon steel seamless elbow needs to be cared for, in addition to the use of solvents for cleaning, but also need to use a brush to polish the steel appearance, to remove loose or oxide skin, rust, welding slag, etc.

Manual rust removal can reach Sa2 level, power rust removal can reach Sa, if the steel surface is attached to the solid oxide sheet, the rust removal effect is not ambitious, and can not reach the depth of anti-corrosion construction.

The pickling of seamless elbows is generally done by chemical and electrolytic methods. The corrosion protection of ceramic composite elbows only uses chemical pickling, which can remove oxide skin, rust, and old coating. Sometimes it can be used as a redisposal after sandblasting. Chemical cleaning can make the surface reach a certain degree of cleanliness and roughness
